Great if you like B&W piccies but colours will show chromatic aberration. Although I have seen some achro's better than others. However, if you want to get into colour pics try to stay clear of achro's. The apo scopes are much better....but more expensive (always comes down to what you're willing to pay).

For an f/5 scope, the Skywatcher is one of the better ones I've seen colour piccies from. Usually, the shorter the FL and faster the scope, the worse the aberration.
